The Box Jellyfish (also known as a Sea Wasp) is a very dangerous creature that inhabits Australian waters. The Jellyfish has extreme toxins present on its tentacles, which when in contact with a human, can stop cardio-respiratory functions in as little as three minutes. This jellyfish is responsible for more deaths in Australian than Snakes, Sharks and Salt Water Crocodiles.

The Irukandji Jellyfish inhabits Northen Australian waters. This is a deadly jellyfish, which is only 2.5 cenimetres in diameter, which makes it very hard to spot in the water.

The Saltwater Crocodile has been reported to grow to lengths of 7 metres!, but the average size of a Saltwater Crocodile is 4 metres long. They are the world's largest reptile and are found on the northern coast of Australia and inland for up to 100 kms or more. They can crush your skull without even trying.

The Taipan is a large, fast, and highly venomous snake often found throughout Australia. The Taipan has the most toxic venom out of all the species worldwide, has a dark brown color and is often found in sugar fields where it hunts for rats.

Another serious threat for those that wish to explore the waters of Australia is the blue-ringed octopus - one of the most toxic sea creatures in the world found off the coast of Australia, New Guinea, Indonesia, and the Philippines. Even though the octopus is only the size of a golf ball, there is no known antidote for its powerful venom. It causes motor paralysis, eventually leading to cardiac arrest.

Known as the most venomous fish in the world, the stone fish lives on the bottom of the reefs, camouflaged as a rock. It lives above the Tropic of Capricorn but can be found in the Queensland Great Barrier Reef as well. It's venom comes from the dorsal area, that is lined with 13 spines, causing shock, paralysis and tissue death depending on the severity of the sting. First aid consists of immobilizing the venom by bandaging the affected area then applying a hot compress. The pain is said to be so excruciating that it leads to amputating the affected limb.

Known as one of Australia's most deadly creatures, the Brown snake has a venom which quickly kills if it goes untreated. Even young snakes are capable of delivering a fatal bite to humans.

The Great White Shark can be found in great numbers on the southern coasts of Australia and, even though they have often been depicted as fatal to humans, they do not target them as a prey. Many of the attacks we're not fatal, the shark only performing test-biting, out of curiosity.

The darkly colored spiders resembling tarantulas have fangs and chelicerae with ample venom glands, that can even penetrate fingernails or shoes. They can be found in the eastern coast of Australia, New South Wales, Victoria or Queensland.

Every time you travel by airplane especially to other countries you run the risk of contracting and spreading a virus where people of that country or your native country haven't developed any immunity towards. To make this even more frightening some viruses can incubate for up to five years so you could feel perfectly healthy when in fact your spreading a viscous virus.

Next, traveling also increases your chances of picking up bed bugs since baggage sits right next to each other for a long time.

The Redback spider (Latrodectus hasselti) is a potentially dangerous spider endemic to Australia. It is a member of the genus Latrodectus, or widow family of spiders, which are found throughout the world. The female is easily recognisable by her black body with a prominent red stripe on the upper side (i.e. the back) of her abdomen. Females have a body length of about a centimetre while the male is smaller, being only 3 to 4 millimetres long. The Redback spider is one of few arachnids which display sexual cannibalism while mating.

Redbacks are considered one of the most dangerous spiders in Australia.[1] The Redback spider has a neurotoxic venom which is toxic to humans with bites causing severe pain. There is an antivenom for Redback bites which is commercially available.

Watch out for the indigenous Maori people of the land. They're often hiding in bushes, completely naked, waiting for passers-by they can strike down with their spears.

This is New Zealand I'm talking about of course. Forgot to mention that.

Bitch, please. And that's only with one bite--where there's one ant, there are bound to be many more.

I've read about those bugs on cracked.com, they are a ritual or something in South America. The young men place their arms in sleeves filled with those ants and keep them on for 10 hours or some time like that, I forgot how long they do it.

Box jellyfish are the most poisonous type of jellyfish and they tend to be near or around the beaches of Australia. If you see a giant net on the beach, never cross it, it's there to keep the jellies out. Sometimes they slip through, these things are very tiny and almost invisible. Their poison is slow, results in paralysis, usually ending in the victim slowly suffocating to death, and yes, you are aware while all of this is happening, and in pain. You can't scream or move either. Just cold, silent agony.
